Which option is the most suitable data set for population growth?

Answer and explanation

Correct answer: Initial population, final population, births, deaths, migration, and time period

Direct answer: A is correct. To study population growth, we need data showing the population at two points in time and the processes that change it. The initial population gives the starting number, while the final population gives the later number. Births add people, deaths reduce the number, and migration can add people to or remove people from an area. The time period is essential because a change has meaning only when we know how long it took; it also allows comparison of growth rates. This data can help describe both the amount and the possible causes of change. B concerns physical geography, C concerns soil and crops, and D describes cultural characteristics. Those data may be useful for other studies, but they do not directly measure population growth. Memory cue: population change = starting number, ending number, births, deaths, migration, and time.
